Dism and removing a "package" from an Installed windows 7 64bit


I am exploring the possibility of removing "packages" from an Installed Windows 7 64bit. It is difficult to test deployment things when items were never installed to being with.


My understanding so far: Microsoft claims that these "packages" are hanging out in bundles of seperated and distinct items for proper compatability, and interoperation of mixed .dll installations. They also claim that the system of belotion allows for an update to a program or system to be removed, reverting the program or system back to the way it was. They also state that only removal of a program will completly remove all the parts and pieces strewn through the system. Ok got that.


Goal: To remove only ONE package, little baby steps, but I could not even accomplish the most simple and observable item. Unfortunatly a search reveals millions of Vista based information resources and few Windows 7 specific, 64bit in my case.


Method #1 , I start as simple as I can


>DISM.exe > C:\packages.txt /online /get-packages

This give me a tiny list of packages (compared to a sysprep list) Below is the only victom of this question, as seen in the packages list.


Package Identity : Microsoft-Windows-LocalPack-AU-Package~31bf3856ad364e35~amd64~~6.1.7601.17514
State : Installed
Release Type : Local Pack
Install Time : 9/21/2011 4:01 AM

The DISM log for that item


2011-10-13 08:34:31, Info                  DISM   DISM Package Manager: PID=3700 Package Microsoft-Windows-LocalPack-AU-Package~31bf3856ad364e35~amd64~~6.1.7601.17514 with CBS state 7(CbsInstallStateInstalled) being mapped to dism state 5(DISM_INSTALL_STATE_INSTALLED) - CDISMPackage::LogInstallStateMapping

This is my failed attempt at uninstalling that package


C:\>dism.exe /image:c:\s2 /remove-package /packagename:Microsoft-Windows-LocalPa
ck-AU-Package~31bf3856ad364e35~amd64~~6.1.7601.17514

This is the error shown (in my world this error says "you have no idea how many steps this is going to take":-)


Deployment Image Servicing and Management tool
Version: 6.1.7600.16385

Error: 2

Unable to access the image.
Make sure that the image path and the Windows directory for the image exist and
you have Read permissions on the folder.

Nowhere in the question , is it asked "Should I be doing this" or "Is this a bad idea" please limit negating comments to the goal of using MS packaging system, some way, or some better way. There is no doubt that I have no idea what I am doing, I am new to this method.


Disclaimer, Every removal of items from the OS has some ramifications, I have a backup ,and I am not afraid to use it. The purpose is for testing only.



Answer



To use dism with a running operating system, you need to specify the /online flag.


Try this:


dism /online /remove-package /packagename:Microsoft-Windows-LocalPack-AU-Package~31bf3856ad364e35~amd64~~6.1.7601.17514

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...
